Apache Spark reassigned SPARK-34601:
------------------------------------
Assignee: Apache Spark
> Do not delete shuffle file on executor lost event when using remote shuffle
> service
> -----------------------------------------------------------------------------------
>
> Key: SPARK-34601
> URL: https://issues.apache.org/jira/browse/SPARK-34601
> Project: Spark
> Issue Type: New Feature
> Components: Shuffle
> Affects Versions: 3.2.0
> Reporter: BoYang
> Assignee: Apache Spark
> Priority: Major
> Labels: shuffle
> Fix For: 3.2.0
>
>
> There are multiple work going on with disaggregated/remote shuffle service
> (e.g. [LinkedIn
> shuffle|https://engineering.linkedin.com/blog/2020/introducing-magnet],
> [Facebook shuffle
> service|https://databricks.com/session/cosco-an-efficient-facebook-scale-shuffle-service],
> [Uber shuffle service|https://github.com/uber/RemoteShuffleService]). In
> those systems, shuffle data will be stored on different server other than
> executor. Spark should not mark shuffle data lost when the executor is lost.
> We could add a Spark configuration to control this behavior. By default,
> Spark still mark shuffle file lost. For disaggregated/remote shuffle service,
> people could set the configure to not mark shuffle file lost.
